Bumps on next-dev:

• Loop c057065 → 417d966: Show and record what Guard + Runway did Loop#2611
• LoopAlgorithm 273fcfe → 3e5c268: Report what Guard + Runway did in AlgorithmOutput LoopAlgorithm#12, Report the guard band's actual depth LoopAlgorithm#13

With Guard + Runway on, the Predicted Glucose screen gets a Guard + Runway row. It shows how far the forecast was lowered and whether the automatic dosing target was lowered. Checking or unchecking the row draws the comparison curve with or without the guard. The Retrospective Correction row notes when the post-low rise cut is active.

Each dosing decision now records what Guard + Runway did (volatility, band depth, runway shift, rise cut), and those values are uploaded to Nightscout and Tidepool with the decision. Nothing changes for anyone with the experiment off.

Test

✅ The change in this PR is to report the effect of Guard + Runway if it is enabled

• This is not a test on the capabilities of the new algorithm experiment

Configuration

Start with LoopWorkspace, next-dev, commit 32fdf0d

• Point to Loop dev branch
• Point to LoopAlgorithm main branch

Test Details

The test phone, SE 3rd gen, iOS 27.0.1, was running the default next-dev, commit 32fdf0d overnight with a glucose pattern consistent with an unannounced meal. (Note the glucose pattern is fixed, and does not respond to the amount of insulin delivered.)

The setting on the phone for algorithm experiments are:

• Guard + Runway enabled
• GBPA disabled
• IRC disabled

Nightscout Dashboard

The screenshot shows the Nightscout dashboard. I figured the predicted decrease in glucose was from the Guard + Runway. That is confirmed by the updated report in the Glucose Prediction view of Loop.

Loop Glucose Prediction

The screenshots below are from the Loop Glucose prediction screen

• left screenshot is the plot with the checkmark for the guard + runway removed
  • this show that without guard + runway, the prediction would be flat instead of below target
• right screenshot has the reported change in forecast
